I was reading the spec sheet on a particular LED and noticed that the viewing angle (2*Θ½) is specified as 30 degrees min and 60 degrees max.
This got me wondering, if I had LEDs with 30 and 60 degree viewing angles, put the same current through them both, will the light emitted from the 60 degree LED have a lower power density?
It seems like it would be lower for the 60 degree LED since the same amount of light is spread out over a greater area, but maybe I am missing something.
